Definitions

  • the invention relates to a plastic-metal composite and a method for its production. These are preferably flat or profile-shaped plastic-metal composite materials, in particular for window and other building profits, as well as for facade, roof and wall profiles or the like.
  • window profiles made of polyvinyl chloride for example, by coextrusion with an aluminum strip provided on the back with heat-activatable adhesive.
  • wall and roof components are known in which polyurethane foam takes over the connection and filling body function between two smooth or trapezoidal profiled sheets forming the top surfaces.
  • metal parts to plastics by giving them a so-called undercut shape, which are embedded in the plastic and form an inseparable connection with it.
  • a method for connecting a layer of a high molecular weight polyamide polymer with a metal layer in which the two layers are pressed together with a reduction in both layers, which is characterized in that the polymer layer before the Compression is baked, that the compression takes place with a reduction to create a green composite and that the green composite is subsequently improved by sintering.
  • DE-PS 19 48 527 describes a floor covering in the form of sheets or tiles, consisting of one or more layers of hair or fibrous material oriented upwards when the covering is laid and a back connected to the back of the lower layer, possibly on is profiled on the outside and which consists of a mixture of at least 27% by weight of a plastic made of polyethylene-acrylic acid ester copolymer mixed with a small amount of bitumen and at least 55 to 60% by weight of coal dust with a grain size of 0 to 30 ⁇ and a proportion of non-combustible components of up to 30 percent by weight, which is characterized in that the back carries a layer of plastic foam on its outside.
  • a web-shaped metallic cover foil for insulation preferably made of aluminum, which is characterized in that it has an additional thin elastic carrier layer made of plastic, which partially melted on the side facing the metal foil is, this melted intermediate layer serves as an adhesive.
  • connection of metal with plastic by gluing has the disadvantage that only well cleaned metal surfaces which have been pretreated to enlarge their surface, with carefully selected and used adhesives, can be processed to composite materials with long-term constant quality properties. Faulty bonds cannot be found apart from a destructive test, a one-off test is almost always impossible.
  • connection defects are so great that large-area bonds with metal surfaces to building construction elements are only very slowly introduced.
  • connection of metal parts with plastics is limited to the embedding of undercuts with threaded bushes and bolts and the like in injection molded and pressed parts.
  • this fear proves to be unfounded in all cases in which the plastic cross section is a high multiple of the metal cross section, that is, thermal stresses lead to the expansion of the metal cross section.
  • the invention has for its object to provide a plastic-metal composite that allows a permanent connection of metal surfaces with plastics of various types, in which doubts about the possible strength and durability are excluded and the one by one inspection by simple inspection can be.
  • the composite side of the metal foils, sheets or mesh is provided with welded-on metal wires, wire mesh, spheres or similar structures which represent undercuts for a plastic enclosing them, into which the material of the base body has flowed in the liquid or dough phase and encloses it in the solidified state.
  • the process for producing the plastic-metal composite material is characterized in that metal wires, wire mesh, balls or similar structures representing undercuts for the penetrating plastic undercuts are welded onto the metal surface facing the plastic surface by the surface of the plastic base body to be connected Heating transferred into a molten or doughy phase and the melted surface leads to embedding under pressure perpendicular to the receiving metal surface and allows it to solidify or cool down.
  • thermoplastics it is also possible, for example in the case of thermoplastics, to heat up the film to be connected to the plastic body in such a way that the plastic surface melts when the heated film is pressed onto it. If the heating of the film is limited so that the heat stored therein is sufficient only for the melting of the metal structures forming the undercuts, which are closely adjacent regions of the plastic body, then particularly rapid connections can be made within a few seconds.
  • the advantages achieved in accordance with the invention are that, instead of procedurally difficult to secure adhesive conditions, two fusion welding processes that can be carried out simply and with proven technologies or, in the case of chemically curing plastics, a combination of fusion welding and subsequent casting or compression molding process are used. They allow the connection of the undercut structures to the back of the metal foil or the sheet metal by roll seam, spot or projection welding or - by sintering and the connection of this surface prepared according to the invention to the plastic surface by coextrusion, melting of the plastic surfaces and indenting the cold or warm undercut surface or by pressing or pouring.
  • connection according to the invention can be checked optically and therefore non-destructively at each interface of the profile or the plate to determine whether the mutual undercut between the metal and plastic surfaces has come about as intended.
  • connection strength according to the design undercut cross-sections is predictable and easily reproducible.
  • FIG. 1 shows a section through a thermoplastic profile with metal surfaces, as could be used for window frames.
  • the metal foils 1 and 2 have on their rear side 5, facing the plastic core 4 of the profile, connected by roller seam welding, longitudinally corrugated wires 3, which are completely flowed around by the plastic melt during the extrusion process and thus embedded in an inseparable manner.
  • Foil thickness, wire diameter, corrugation height and length, as well as welding cross-section are dimensioned according to the usage requirements.
  • Fig. 2 shows a cross section through a plate-shaped, glass fiber reinforced thermoset profile, as it can be used as a facade or roof element.
  • the foils 6 and 7 have a wire mesh 8 fastened by roller seam welding, which is pressed into the glass fiber rovings 9 impregnated with suitable impregnating resins, i.e. strands consisting of glass threads without substantial rotation, and pressed in by the hardened impregnating resins and partially enclosed by the glass fibers 9 is.
  • FIG. 3 shows a cross section through a thermoplastic profile according to FIG. 1, in which the method according to the invention is used to connect two profile sections, for example at the corners to a window frame.
  • the plastic core 4 of the profile shows metal foils 1 and 2, the rear sides 5 of which have longitudinally corrugated wires 3 which are embedded in the profile core 4.
  • the butt joint 10 between the two profile pieces 11 and 12 is covered by a coarse-mesh fabric 13 thicker wires welded at the cross points of the weft 14 and chain 15, which, heated in an alternating electromagnetic field, was melted into the profile inner walls 17 and 18 by spreading devices 16 .
